The trail, called a ``Parcours`` (a heart court), extends for more than a mile and includes 20 exercise stations. It is located at the YMCA, 6631 Palmetto Circle. One can walk or jog between stations. Simple instructions are posted at each station with suggestions as to the number of repetitions to do the exercise properly.

The facility, which officially opened Thursday, is available to the public free of charge.

``It`s something people can do without a guide,`` Seewald said.

Seewald said that the trail was donated by the American Heart Association. She added that the course costs $6,700. Seewald said that staff members of the YMCA, its board members and members of the Sunrise and Kiwanis clubs built the course in four weekends.

Seewald said the facility is the only one in the Boca Del Mar portion of the county.

``Since fitness has become more popular, people are concerned with keeping in shape,`` she said, noting that the benefit from the exercises is getting better cardiovascular and respiratory conditioning.

``It doesn`t cost (the user) money,`` she said.

Kathy Dickenson, a volunteer with the American Heart Association for Palm Beach County, said there is a another heart trail at Lake Wyman Park (located off of the intracoastal at Northeast Fifth Avenue).

``Because of the incredible upswing in the interest in physical fitness, there has been a benefit across the board in the old and young,`` Dickenson said. ``It`s designed to increase heart rate and you can go at your own pace.``

The jogging trail permits the development of physical fitness.

``It`s simple exercises and you work up to the more difficult ones and then cool down,`` said Virginia McVey, executive director of the American Heart Association`s Palm Beach County chapter.
